What is the maximum interval for supporting and securing type MC cable in manufactured wiring systems?

8 ft
4 ft
6 ft
10 ft

The correct answer is: 6 ft

The correct interval for supporting and securing type MC (Metal Clad) cable in manufactured wiring systems is indeed 6 feet. The National Electrical Code (NEC) provides specific guidelines for securing various types of cables to ensure safety and proper installation. For type MC cable, particularly, maintaining a support interval of 6 feet helps to prevent undue stress on the cable, reduces the risk of mechanical damage, and ensures that the installation adheres to the code requirements. This requirement is crucial for maintaining the integrity of electrical systems, especially in environments subject to movement or vibrations. Compliance with this interval helps electricians avoid potential hazards associated with loose or unsecure wiring, which can lead to failures, shorts, or other electrical issues. Understanding and applying these regulations is essential for both exam success and on-the-job safety and efficiency.
